5 CFR 551.421 : Administrative Personnel (§ 1.1 To Parts 10003-10049) — (§ 1.1 To Parts 631-699) — Office Of Personnel Management (§ 1.1 To Parts 631-699) — Civil Service Regulations (§ 110.101 To Parts 631-699) — Pay Administration Under The Fair Labor Standards Act (§ 551.101 To § 551.710) — Hours Of Work (§ 551.401 To § 551.432) — Application Of Principles In Relation To Other Activities (§ 551.421 To § 551.426) — Regular working hours.

(a) Under the Act there is no requirement that a Federal employee have a regularly scheduled administrative workweek. However, under title 5 United States Code, and part 610 of this chapter, the head of an agency is required to establish work schedules for his or her employees. In determining what activities constitute hours of work under the Act, there is generally a distinction based on whether the activity is performed by an employee during regular working hours or outside regular working hours. For purposes of this part, “regular working hours” means the days and hours of an employee's regularly scheduled administrative workweek established under part 610 of this chapter.

(b) [Reserved]
